You can use BlackStar. It will display your current coordinates, there is a menu item to copy the coordinates to your clipboard. You can then open an email and past them in.
In the future, maybe not distant, you will just click one button and BlackStar will open an email or text for you to address then send.
Gpslogger is a sweet little program to. Latitude blows if you ask me. It only shares cell tower location unless you have gmaps up and active on your phone. If you want to see where someone is and they have gmaps running in the background on there phone, all you going to see is a approximate location. Plus, it updates too infrequenty...

There is an application that I downloaded from Blackberry App World called "Carfinder" by neosistic.com. It is a great app that gives your present coordinates and saves them so you can use those coordinates to find your vehicle......You can also send those coordinates to people via email. The app also has a compass to show you where you are going so you can find your car.....Oh, and the best thing is......it's FREE.
